Absolute dating is expensive and takes time while relative dating is less-expensive and efficient.
The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.Absolute age is a quantitative measurement while relative age is a qualitative measurement.Absolute dating works better for igneous and metamorphic rocks while relative dating works better for sedimentary rocks having layered arrangement of sediments.Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.The comparison helps establish the relative age of these remains.
